Lorraine Property sales

My mother rented a house for 16 years when she stayed there only one plate of a stove worked she complained to the owner he didn't care then the owner let Lorraine property take over the lease my mom complained to Lorraine that use to work for them as the plate wasn't warming up properly anymore and that the stove needs rewiring still nothing now they want my mom to repair it after she asked them in 2011. Now they're complaining that she put it outside but there was no space for another stove in the tiny kitchen and no garage. After moving out theyre are complaining about faults that were not there.
